Essential HVAC Equipment Guide: Complete Tool & Vehicle List (2026)
Starting an HVAC business or equipping a new technician? This complete equipment guide covers everything you need from basic hand tools to diagnostic equipment, van setup, and realistic budget breakdowns. Based on real costs from UK suppliers in 2026.
⚠️ Not Professional Licensing Advice
Professional licensing requirements are legal obligations that change over time. This guide provides general information only and should not be relied upon as definitive guidance.
Before undertaking any licensed work: Verify current requirements directly with the relevant regulatory body (Gas Safe Register, NICEIC, etc.). Qualification codes, scope of work, and legal requirements may have changed since this guide was published.
Working without proper licenses can result in prosecution, fines, imprisonment, and invalidation of insurance coverage.

💡 Pro Tip: Tool Quality
Buy professional-grade hand tools (Knipex, Wera, Klein) upfront. They cost 2-3x more than DIY brands but last 10+ years. Budget tools break on commercial jobs and cost more long-term through replacements and lost time.
Power Tools (£600-£900)
Essential Power Tools
| Tool | Use Case | Cost |
|---|---|---|
| Cordless drill/driver (18V) | Mounting units, ductwork, general drilling | £120-£180 |
| Impact driver (18V) | Heavy-duty fastening, lag bolts | £100-£150 |
| Reciprocating saw | Cutting old ductwork, demolition | £80-£130 |
| Angle grinder (115mm) | Cutting metal, grinding welds | £60-£100 |
| Cordless vacuum (18V) | Site cleanup, duct cleaning | £80-£120 |
| Soldering torch/brazing kit | Copper pipework, refrigeration lines | £100-£180 |
| Battery charger & 2x spare batteries | Keep working all day | £80-£120 |
🔋 Battery Platform Strategy
Stick to ONE battery platform (Milwaukee, DeWalt, Makita). Batteries cost £50-£80 each. A single 18V platform means 2-3 batteries power all your cordless tools.
Recommended: Milwaukee M18 or DeWalt 18V XR for HVAC work. Both have excellent range, tough enough for commercial sites, and 3-year warranties.
Diagnostic Equipment (£1,500-£3,000)
Essential Diagnostic Tools
Electrical Testing
- Digital multimeter (HVAC-specific): £60-£150 - Fluke 117 or Amprobe AM-530 with HVAC temperature functions
- Clamp meter: £80-£180 - Essential for measuring current draw on motors and compressors
- Voltage tester (non-contact): £15-£30 - Quick safety checks before working
- Megohmmeter (insulation tester): £150-£300 - Testing motor windings and cable insulation
HVAC-Specific Diagnostics
- Manifold gauge set (digital): £200-£450 - Testo 550 or Fieldpiece SMAN series for refrigeration diagnostics
- Thermometer (infrared): £40-£100 - Non-contact temperature readings for ducts and components
- Combustion analyser: £400-£800 - Required for gas boiler servicing and commissioning
- Gas leak detector: £80-£200 - Refrigerant and natural gas detection
- Psychrometer (humidity meter): £60-£150 - Measuring indoor air quality and system performance
- Manometer (digital): £100-£250 - Gas pressure testing and static pressure readings
Advanced Diagnostics (Optional Year 1)
- Thermal imaging camera: £300-£1,200 - Spot heat loss, electrical faults, blocked ducts (ROI: helps sell insulation upgrades)
- Inspection camera/borescope: £80-£200 - Visual inspection inside ducts and heat exchangers
- Airflow hood: £400-£900 - Balancing air distribution systems (buy when you start commercial work)
⚠️ Calibration Requirements
Combustion analysers and gas detectors require annual calibration (£80-£150 per device). Budget for this ongoing cost. Using uncalibrated equipment on gas work can invalidate your Gas Safe registration and insurance.
Refrigeration Tools (£800-£1,500)
Essential Refrigeration Equipment
| Equipment | Purpose | Cost |
|---|---|---|
| Vacuum pump (2-stage, 5 CFM) | Evacuating refrigeration systems | £250-£450 |
| Recovery machine | Legally required for refrigerant recovery | £400-£800 |
| Refrigerant scale (electronic) | Accurate charging of systems | £80-£150 |
| Recovery cylinders (various sizes) | Storing recovered refrigerants | £100-£200 |
| Flaring tool kit | Creating leak-free pipe connections | £60-£120 |
| Swaging tool set | Expanding copper pipe ends | £40-£80 |
| Tube bender (lever type) | Bending copper without kinking | £50-£100 |
| Nitrogen regulator & hose | Pressure testing and brazing purge | £80-£150 |
🚨 Legal Requirement: F-Gas Certification
You cannot legally purchase or handle refrigerants in the UK without F-Gas certification (Category I minimum). Certification costs £300-£600 for training + exam.
Buying refrigeration equipment without F-Gas is pointless - you won't be able to buy refrigerant or legally charge systems. Get certified BEFORE buying this equipment.
Safety Equipment (£300-£500)
Required Safety Gear
Personal Protective Equipment
- Safety boots (composite toe, electrical rated) - £60-£120
- Work gloves (leather & insulated) - £20-£40
- Safety glasses/goggles - £10-£25

- Lockout/tagout kit - £25-£50
- Gas detector (portable CO monitor) - £80-£150
- Safety harness & lanyard (for rooftop work) - £60-£120
💼 Insurance Requirements
Most public liability insurance policies require you to have and use appropriate PPE. Working without proper safety equipment can invalidate your insurance coverage. Keep receipts and photo evidence of your safety gear.
Van Equipment & Storage (£1,200-£2,000)
Van Organization System
Shelving & Storage
- Van racking system (professional): £600-£1,200 - Bott, Sortimo, or Van Vault systems. Custom-fit to your van.

- Step ladder (3-step & 6-step): £40-£100 - Compact enough to fit in van
- Extension ladder (2-section): £80-£200 - For external unit access
- Dust sheets & floor protection: £30-£60 - Customer property protection
🚐 Van Racking ROI
Professional van racking costs £600-£1,200 installed, but saves 15-20 minutes per job through better organization. That's 1.5-2 hours per day, or an extra job per week.
At £200 per job, proper racking pays for itself in 6-10 jobs (2-3 weeks). Plus it looks professional when customers see your van and prevents tool damage.
Consumables & Materials (£400-£600)

📦 Stock Management Strategy
Don't overbuy consumables upfront. Start with £400-£600 of basics, then restock weekly based on actual job requirements.
Track every item used per job in your field service software (like Toolfy). After 2-3 months you'll know exactly what moves fast vs. what sits in the van unused.
Van Selection Guide
Recommended Vans for HVAC Work
| Van Model | Size | Best For | Cost (Used 3-5yr) |
|---|---|---|---|
| Ford Transit Custom | Medium (L1H1) | Solo operator, residential work | £12,000-£18,000 |
| VW Transporter T6 | Medium (SWB) | Premium image, residential | £15,000-£22,000 |
| Mercedes Vito | Medium-Long | Reliability, mixed work | £13,000-£20,000 |
| Ford Transit (full size) | Large (L2H2) | Commercial installs, 2+ crew | £10,000-£16,000 |
| Vauxhall Vivaro | Medium | Budget option, good payload | £9,000-£14,000 |
Van Size Considerations
Small Van (Car-derived, Berlingo/Partner)
Pros: Cheap to run (40+ MPG), easy parking, lower insurance
Cons: Too small for HVAC equipment. You'll need pipe racks on top, limited tool storage. Fine for maintenance-only, terrible for installs.
Medium Van (Transit Custom, Vito) - RECOMMENDED
Pros: Perfect for solo HVAC tech. Fits all tools, ladders, small AC units, boilers. Good MPG (30-35). Easy to drive/park.
Cons: Tight fit for large commercial units. Need external pipe racks.
Large Van (Transit L2H2/L3H2)
Pros: Huge payload. Internal pipe storage. Can carry large AC units, ductwork. Room for 2-3 crew.
Cons: Expensive to run (25-28 MPG). Parking challenges. Higher insurance. Overkill for solo residential work.
🚐 Start Medium, Scale Up
For solo HVAC startups: Buy a used medium van (Transit Custom, Vito) 3-5 years old with under 100k miles. Budget £12,000-£18,000.
You can do 90% of residential HVAC work from a medium van. Only upgrade to large when you're consistently turning down commercial installs due to van size, or hiring a second person.

Smart Buying Strategies
New vs Used Equipment
| Item | Buy New or Used? | Why |
|---|---|---|
| Hand tools | New | Lifetime warranty, known condition, safety-critical for electrical work |
| Power tools | Either | Buy refurbished from manufacturers with warranty (saves 30-40%) |
| Diagnostic equipment | New | Requires calibration certificates, warranty essential for accuracy |
| Van | Used | 3-5 year old saves £15k-£20k, reliable with service history |
| Van racking | New | Custom-fit to your van, professional finish, ROI within weeks |
| Refrigeration tools | New | Legal compliance issues with used recovery equipment, warranty critical |
| Ladders & access | Either | Check for damage/wear, but good used ladders save 40-50% |
